  Abstract:
We study the phase diagram of the flux lines using the mapping to two-dimensional bosons interacting via the Yukawa potential in the hypernetted-chain approximation. The pair-correlation function, static structure factor, and spectrum of the excited energies are calculated over a wide range of the parameter. These quantities are used for studying the freezing transition from the entangled vortex liquid into the Abrikosov lattice. The resulting B-T phase diagram is in good agreement with the known estimates for the vortex lattice phase diagram and the Monte Carlo simulations.
